"PERFORMANCE VENTSTM”
FOR HEAD BREATHERS
These beautifully engineered & machined breathers do much more than
just vent your engines fumes! For starters, they have the US
Patented Crank Case Vacuum Valve built into them. So instead of just
looking good but blowing oil all over you & your engine, these vents
actually perform! The crank case vacuum they produce results in
greater engine efficiency, faster response, better ring seal, no
weeping gaskets, plus other advantages.
The
303 stainless steel bolts, designed by ET, have machined bosses so
mounting brackets, breather holes, & vents align perfectly with the
vent eyelets.
Essentially a one-piece design, there is nothing to vibrate loose so
you won't find them bouncing along the road besides you! Rotate 180
degrees for a plain look with vents hidden.
Best
of all, they are designed by ET Performance & Racing Products, who
brought you the original crank case vacuum valves (KrankVents) & are
made in the USA, of course! Guaranteed performance!
Available for all head breathers: Big Twin, XL's, & Twin Cam
engines, of any displacement. Complete with ET’s special
Stainless Steel bolts, washers (plus extras), instructions.
PV1: Single vent, bolt, washers, complete (only one is needed for
any size engine)
PV2: Set of two, complete (2 PV’s look cool, or 1 for a buddy & save
either way)

Metric Riders & Racers!
Having
trouble staying with the factory teams or just want to cure
the oil blowing out of your cruiser!! From Ducati to Yamaha
Road Stars, to high-twisting 14,000+ rpm inline 4’s, you
won't believe the results!! Top racers have tried all the
knock-off valves & they report they couldn’t hang! “We now
run with, & beat, factory sponsored teams (Over 100 wins
Daytona & Willow Springs!). The other crank case valves we
tried literally disintegrated! The KrankVent™ never stops
performing!!”
Available w/ 9.5mm or 12.7mm hose barbs. Some engines, like
the Honda VTX 1800R, use a ½” (12.7mm) hose. Some Ducati’s,
& Top Fuel bikes use a 1” ID hose & require using two 1”
lengths of the original hose to neck it down to ½” ID.
Engine vacuum will not be altered using this procedure!
Questions on race engines or street; check out R1, Roadstar,
Kawa, Ducati, etc. forums or call ET’s Cell 805.895.2679
(Pacific Time) for a specific application. We have helped
put many racers “In the Winners Circle” with smoother
response, faster acceleration, empty catch cans,
etc.! These lightweight KV’s are often preferred by top road
race teams!
